Truck Tent

Ive been looking at some truck tents recently and searched through some threads here and have found a few answers.

Ive been looking at the Napier Back Roadz tent. I have an 01 Tacoma double cab and I was wondering if anyone has used this set up and how it fits in the short bed. Also I have had a hard time finding an air mattress that fits with the way the bed is set up. I would appreciate if anyone has any experiance or info since the website is knda vauge on info.
